Bollywood celebrities including Shah Rukh Khan, Shabana Azmi, Akshay Kumar and Anupam Kher have offered condolences to the victims of the Amarnath Yatra terror attack and demanded a strong action against the perpetrators.

On Monday night, seven pilgrims - six women, one man - were killed and 19 others injured when militants attacked an unescorted bus at Khanabal, Anantnag district on the Srinagar-Jammu highway. All the victims hailed from Gujarat.

The bus was returning from Baltal to Mir Bazar after darshan. The militants also carried out two attacks on security forces in the area.
